/*
* CharStrings are encoded following the the CharString Encoding sequence

* The value in a byte indicates a command, a number, or subsequent bytes
* that are to be interpreted in a special way.
*
* CharString Number Encoding:
* A CharString byte containing the values from 32 through 255 inclusive
* indicate an integer. These values are decoded in four ranges.
*
* 1. A CharString byte containing a value, v, between 32 and 246 inclusive,
* indicate the integer v - 139. Thus, the integer values from -107 through
* 107 inclusive may be encoded in single byte.
*
* 2. A CharString byte containing a value, v, between 247 and 250 inclusive,
* indicates an integer involving the next byte, w, according to the formula:
* [(v - 247) x 256] + w + 108
*
* 3. A CharString byte containing a value, v, between 251 and 254 inclusive,
* indicates an integer involving the next byte, w, according to the formula:
* -[(v - 251) * 256] - w - 108
*
* 4. A CharString containing the value 255 indicates that the next 4 bytes
* are a two complement signed integer. The first of these bytes contains the
* highest order bits, the second byte contains the next higher order bits
* and the fourth byte contain the lowest order bits.
*
*
* CharString Command Encoding:
* CharStrings commands are encoded in 1 or 2 bytes.
*
* Single byte commands are encoded in 1 byte that contains a value between
* 0 and 31 inclusive.
* If a command byte contains the value 12, then the value in the next byte
* indicates a command. This "escape" mechanism allows many extra commands
* to be encoded and this encoding technique helps to minimize the length of
* the charStrings.

/**
* A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
* tasks are specified as parameters to the function, after the usual callback
* parameter, with the parameter names matching the names of the tasks it
* depends on. This can provide even more readable task graphs which can be
* easier to maintain.
*
* If a final callback is specified, the task results are similarly injected,
* specified as named parameters after the initial error parameter.
*
* The autoInject function is purely syntactic sugar and its semantics are
* otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
*
* @name autoInject
* @static
* @memberOf module:ControlFlow
* @method
* @see [async.auto]{@link module:ControlFlow.auto}
* @category Control Flow
* @param {Object} tasks - An object, each of whose properties is a function of
* the form 'func([dependencies...], callback). The object's key of a property
* serves as the name of the task defined by that property, i.e. can be used
* when specifying requirements for other tasks.
* * The `callback` parameter is a `callback(err, result)` which must be called
* when finished, passing an `error` (which can be `null`) and the result of
* the function's execution. The remaining parameters name other tasks on
* which the task is dependent, and the results from those tasks are the
* arguments of those parameters.
* @param {Function} [callback] - An optional callback which is called when all
* the tasks have been completed. It receives the `err` argument if any `tasks`
* pass an error to their callback, and a `results` object with any completed
* task results, similar to `auto`.
* @example
*
* // The example from `auto` can be rewritten as follows:
* async.autoInject({
* get_data: function(callback) {
* // async code to get some data
* callback(null, 'data', 'converted to array');
* },
* make_folder: function(callback) {
* // async code to create a directory to store a file in
* // this is run at the same time as getting the data
* callback(null, 'folder');
* },
* write_file: function(get_data, make_folder, callback) {
* // once there is some data and the directory exists,
* // write the data to a file in the directory
* callback(null, 'filename');
* },
* email_link: function(write_file, callback) {
* // once the file is written let's email a link to it...
* // write_file contains the filename returned by write_file.
* callback(null, {'file':write_file, 'email':'user@example.com'});
* }
* }, function(err, results) {
* console.log('err = ', err);
* console.log('email_link = ', results.email_link);
* });
*
* // If you are using a JS minifier that mangles parameter names, `autoInject`
* // will not work with plain functions, since the parameter names will be
* // collapsed to a single letter identifier. To work around this, you can
* // explicitly specify the names of the parameters your task function needs
* // in an array, similar to Angular.js dependency injection.
*
* // This still has an advantage over plain `auto`, since the results a task
* // depends on are still spread into arguments.
* async.autoInject({
* //...
* write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {
* callback(null, 'filename');
* }],
* email_link: ['write_file', function(write_file, callback) {
* callback(null, {'file':write_file, 'email':'user@example.com'});
* }]

/**
* Creates a `lodash` object which wraps `value` to enable implicit method
* chain sequences. Methods that operate on and return arrays, collections,
* and functions can be chained together. Methods that retrieve a single value
* or may return a primitive value will automatically end the chain sequence
* and return the unwrapped value. Otherwise, the value must be unwrapped
* with `_#value`.
*
* Explicit chain sequences, which must be unwrapped with `_#value`, may be
* enabled using `_.chain`.
*
* The execution of chained methods is lazy, that is, it's deferred until
* `_#value` is implicitly or explicitly called.
*
* Lazy evaluation allows several methods to support shortcut fusion.
* Shortcut fusion is an optimization to merge iteratee calls; this avoids
* the creation of intermediate arrays and can greatly reduce the number of
* iteratee executions. Sections of a chain sequence qualify for shortcut
* fusion if the section is applied to an array of at least `200` elements
* and any iteratees accept only one argument. The heuristic for whether a
* section qualifies for shortcut fusion is subject to change.
*
* Chaining is supported in custom builds as long as the `_#value` method is
* directly or indirectly included in the build.
*
* In addition to lodash methods, wrappers have `Array` and `String` methods.
*
* The wrapper `Array` methods are:
* `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
*
* The wrapper `String` methods are:

*
* The wrapper methods that support shortcut fusion are:
* `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
* `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
* `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
*
* The chainable wrapper methods are:
* `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
* `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,
* `commit`, `compact`, `concat`, `conforms`, `constant`, `countBy`, `create`,

/**
* Creates a throttled function that only invokes `func` at most once per

* method to cancel delayed `func` invocations and a `flush` method to
* immediately invoke them. Provide `options` to indicate whether `func`
* should be invoked on the leading and/or trailing edge of the `wait`
* timeout. The `func` is invoked with the last arguments provided to the
* throttled function. Subsequent calls to the throttled function return the
* result of the last `func` invocation.
*
* **Note:** If `leading` and `trailing` options are `true`, `func` is
* invoked on the trailing edge of the timeout only if the throttled function
* is invoked more than once during the `wait` timeout.
*
* If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
* until to the next tick, similar to `setTimeout` with a timeout of `0`.
